Overview
The WiFi Access Point transmits messages from the
computer to the Bridge unit located near the sign. The
Bridge receives the wireless message signal from the
the Access Point and sends them to the sign for display.
These instructions explain how to replace an Access
Point (AP) or Bridge unit connected to an Excite,
RoadStar, or StreetSmart sign that is using Ooh!Media
software.
Replacing the AP or Bridge unit consists of three steps:
• Step 1 - Configure the AP or Bridge
• Step 2 - Replace the AP or Bridge
• Step 3 - Send a test message
If you need assistance during the replacement, contact
Adaptive’s Technical Support team at (414) 357-2020
extension 519.

Troubleshooting
If nothing appears on the sign when you send messages from Ooh!Media, the first step is to verify there is
communication with the sign. You can do this by “pinging” the sign. Ping is a tool used on computer networks to
test whether devices are reachable. The goal of pinging a device is to get a reply. If there is no reply, the ping
request “times out” meaning the device is unreachable. See “To ping the sign, Bridge, or Access Point” on this
page for instructions.
If you can successfully ping the sign, then the WiFi devices are communicating properly.
